Lincoln Riley is already making moves.
The new Oklahoma head coach secured the services of Ron Tatum III on Monday, as the four-star defensive end announced he's decommitting from Texas in order to join the Sooners.
Tatum seemed set on playing for Tom Herman and Co. back in April, but the pass-rusher and Oklahoma native must have been swayed by Riley taking over the head coaching duties in Norman.
The No. 77-ranked recruit on the ESPN 300 for the 2018 class also ranks as the No. 2 player in Oklahoma, and the eighth overall defensive end.
Riley's head coaching tenure for the Sooners isn't even a week old but the fact he's flipping commitments from the program's greatest rival has to be pleasing fans thus far.
